Spoofing calls account for a large percentage of unwanted nuisance calls. This is a widespread issue impacting all phone service providers. Regrettably, anyone with internet access can use 3rd party software to disguise the source of a call. And it is typically impossible to trace the source due to the calls originating from the internet.
To further explain, spoofing happens when the calling party uses a paid service (like Spooftel, Spoofer or Spoof Card), which allows the calling party to change the message sent as Caller ID.
